Scientists discover the motion of sperm cells using 3-D technology

If nature finds the best way, then move in a spiral pattern to get there the quickest, from the UCLA Newsroom:

The team developed a lensless computational imaging platform that accurately tracked more than 24,000 individual sperm cells in a large volume 타로카페 다운로드. This involved observing the individual rotations of each sperm cell, including helical movement patterns, rotation speed, and linear and curved distances traveled 배치 파일.

90% of them move in a right-handed spiral – damn I’m left-handed – and they move fast for microscopic entities, 20-100 micrometers/second 다운로드.

That’s a big difference in speed…one sperm cell could be 5x faster than his brother.

Facebook goes native! Releases new apps that are twice as fast

Facebook has finally answered the question that’s been bugging Wall Street and the rest of us, “when are you going to get mobile?”

Yesterday, the answer came as Facebook launched major upgrades to their iPhone and iPad apps 다운로드. From the N.Y. Times Bits blog:

Those who have suffered from the sluggishness of the current apps can breathe a collective sigh of relief: these new versions are much faster 다운로드.

The apps look nearly identical to their predecessors. The main difference is that most of their old Web-based code has been replaced with the native programming code used for iOS

Even more, Facebook has gone all Google Plus on the issue (you know Google making social everyone’s responsibility):

In recent interviews, Facebook executives said they have retooled the organization so that every product team is working on mobile, and the company holds weekly training courses on programming for Apple and Android devices 다운로드.

 

The Verge is reporting that these updates make the apps twice as fast:

In building a native Facebook app for iOS, the company looked at improving three key places, “the app’s largest pain points” all relating to speed: launching the app, scrolling through the News Feed, and tapping photos inside the News Feed 다운로드. “We’re twice as fast in all these areas,” Mick Johnson says.

 

I’ve been playing with the app and the claims appear to be true 다운로드. This is good news for Facebook fans (and stock holders) because slow apps can be killer for growth.

 

**Sorry for the “native” joke, but I couldn’t resist 🙂

Speed record set for all-electric airplane – 204.4 mph

Chip Yates does not like sitting still. Just a day after piloting his electric-powered Long EZ airplane to over 200 miles per hour – making him the fastest electric-airplane pilot in the world – he had to disassemble the airplane, pack it up and drive 2,000 miles east to Oshkosh, Wisconsin 리얼 스틸 apk. Here at Airventure, Yates continues to be busy answering questions about his record-setting run. And perhaps one of the more surprising answers is that Yates is a not a veteran test pilot 다운로드. He just got his license in June and has about 58 hours of experience, including the record-setting run last week.

When the electric vehicle pioneer bought the used airplane it had a 118 horsepower, four-cylinder gasoline-powered engine that is fairly standard for a Long EZ 다운로드. Over the course of several months Yates and his team pulled the four-cylinder engine out of the Long EZ. They then pulled the 193 kW (258 hp), liquid cooled electric motor out of his record setting battery powered motorcycle and mounted it to the back of the Long EZ realtek HD 오디오 관리자.

With the very well used (Yates calls it “abused”) lithium polymer battery back from the motorcycle in the back seat, the Long EZ was being prepared as a test bed for some of the technologies Yates needs to develop for his transatlantic flight 다운로드. But after setting speed records for an electric motorcycle, first up for the Long EZ was a speed run.

BMW shows off an electric scooter with 62 mile range, 75 mph speed, & 3-hour charge

A new BMW prototype is looking to split the difference between speed and range in electric scooters. BMW’s C Evolution, which the company recently presented as a “near-production prototype” in London, is a stylish but pretty ordinary-looking scooter that charges through sockets or a dedicated station 타로카페 다운로드.

Its three-hour charge time gives users up to 100 kilometers (62 miles) of range, BMW says, and it can reach speeds of 120 kilometers per hour (75 miles per hour) 배치 파일.

“BMW has read the signs of the times and is expanding its business activities to include the facet of urban mobility 다운로드. Electromobility has a key role to play in this new segment.”

The best video NASA has ever produced – ‘7 minutes of terror’ – landing a robot on Mars

 

On Aug 다운로드. 5 or Aug. 6, depending on which part of the country you’re in, the Curiosity spacecraft careening toward Mars will hit the Red Planet’s atmosphere, deploy a supersonic parachute and either land safely on the planet’s surface or perish 다운로드. It’s dramatic stuff, and NASA has produced this Hollywood-style YouTube video, complete with animation and suspenseful music, to preview the landing, evoke that drama and put viewers on the edge of their seats 다운로드.

As engineers explain, it will take seven minutes for Curiosity to travel from the edge of Mars’ atmosphere to the surface, going from a speed of 13,000 mph to zero 2010 엑셀 무료. “If any one thing doesn’t work just right, it’s game over,” engineer Tom Rivellini says.

Because Mars is so far away, it actually takes 14 minutes for the spacecraft’s signal to reach Earth 다운로드. So by the time we learn the spacecraft has hit the top of Mars’ atmosphere, Curiosity will have either have survived the landing or perished for a full seven minutes 패러렐 즈 무료 다운로드.

Sign up for Google Fiber get a free Nexus tablet, or super-cheap internet for $3.57/mo

Today may very well live in infamy as the day the cable companies died. Internet giant Google announced its new, groundbreaking Google Fiber, a broadband service that will bring breakneck 1Gbps internet speed to Kansas City — service far faster and far cheaper than that offered by traditional cable companies 박효신 야생화.

How fast is Google’s 1Gbps service? Competitor Comcast recently announced it would launch 305Mbps speed service to much of the Northeast at a cost of $299.95 per month…at 1,000 Mbps, Google Fiber cost of just $70 per month 다운로드.

Google Fiber allows you to combine your cable TV and internet service into one product, for just $120 per month. Getting service to your house will require you pay a $300 service initiation fee — a fee that’s waved if you agree to keep Google Fiber service for a minimum of two years 다운로드.

And the remote control for your Google Fiber TV service? It’s a Nexus 7 tablet.

If you’re looking for a lower priced internet option, Google Fiber has you covered there, too 아기 상어 mp3 다운로드. Anyone who pays the $300 connection fee can opt to receive 5Mbps service for free for seven years. That’s an unheard of bargain — you can essentially buy seven years’ worth of internet service for just $3.57 a month 다운로드.

Robot cheetah sets speed record for legged robots

This video shows a demonstration of the “Cheetah” robot galloping at speeds of up to 18 miles per hour (mph), setting a new land speed record for legged robots 다운로드. The previous record was 13.1 mph, set in 1989.

The robot’s movements are patterned after those of fast-running animals in nature. The robot increases its stride and running speed by flexing and un-flexing its back on each step, much as an actual cheetah does 다운로드.

The current version of the Cheetah robot runs on a laboratory treadmill where it is powered by an off-board hydraulic pump, and uses a boom-like device to keep it running in the center of the treadmill 저스티스리그 자막 다운로드. Testing of a free-running prototype is planned for later this year.

 

I can’t explain why but watching this video makes me very scared 다운로드. I think someone needs to make a horror movie with speedy robot cheetahs to haunt my nightmares.

This description of the robotics program doesn’t help any:

Robots hold great promise for amplifying human effectiveness in Defense operations 한국 책 다운로드. Compared to human beings and animals, however, the mobility and manipulation capability of present day robots is poor. In addition, design and manufacturing of current robotic systems are time consuming, and fabrication costs remain high 카와이헌터 다운로드. If these limitations were overcome, robots could assist in the execution of military operations far more effectively across a far greater range of missions 베스트 오브 미.
